    canned-wks: use GPT partition table
    
    According to UEFI specification all EFI platforms must support
    GUID Partition Table(GPT) disk layout. Here is a list of advantages
    of using GPT disk layout over the legacy MBR partitioning:
    
     - Logical Block Addresses (LBAs) are 64 bits (rather than 32 bits).
     - Supports many partitions (rather than just four primary partitions).
     - Provides both a primary and backup partition table for redundancy.
     - Uses version number and size fields for future expansion.
     - Uses CRC32 fields for improved data integrity.
     - Defines a GUID for uniquely identifying each partition.
     - Uses a GUID and attributes to define partition content type.
     - Each partition contains a 36 character human readable name.
    
    Used GPT partitioning in all EFI kickstart files.
    Tested result images on NUC, MinnowBoard MAX and MinnowBoard Turbot.
